Abstract
The invention relates to a novel formation method of a high-capacity lead storage battery. A standing step is added between process operation steps of direct sequence conversion of charging and discharging; the operation process mode of the direct-current charging and discharging machines participating in parallel operation is not changed, charging, discharging or standing is carried out, the operation time is not changed, the sum of operation currents of the charging and discharging machines participating in parallel operation is a process specified value, and the operation starting time interval of the first charging and discharging machine and the last charging and discharging machine is smaller than newly-added standing time in the process. According to the novel formation method of the high-capacity lead storage battery, the demand quantity of large-specification direct-current charging and discharging machines is reduced, and the utilization rate of small-specification direct-current charging and discharging machines is increased.
Description
technical field [0001] The invention relates to the field of energy storage battery systems, in particular to a novel formation method of a large-capacity lead storage battery. Background technique [0002] In the production process of lead-acid batteries, the process of multiple DC charging, DC discharging and standing still is called formation, and the main equipment in the formation process is a DC charging and discharging machine. [0003] Different battery formation process steps are different, and the operating current and time of each step are different. In order to ensure the consistency of the product, the process requires that the process deviation of the battery charging and discharging current value should be less than 1%. The operating current of the DC charging and discharging machine needs to be The control is within the range of 10% to 90% of the full operating range, which has led to battery factories purchasing DC charging and discharging machines of many s...
